Agreed. It may just be semantics but I can see how "oppose" might imply the active use of outside force or energy, as opposed to a passive consumption of energy.

In fact, "resists" (as in resistor) or "impedes" (as in impedance) are probably the most excellent words to use!

 

The critical point for the OP's question is that a resistor affects the energy balance, but not the mass (charge) balance. The flow of charge on either side of the resistor is unchanged, just like the water flow on either side of a flow restriction. The energy, however, is diminished on the low side.

 

mmy question is if resistor opposes current then why current before the resistor and after resistor same although it opposes current...iam very confuse someone plz answer

This depends on the method of delivery of the resistance in the circuit
Because it's about the change in the energy
Because if there was no change in the energy, there will be no change in the current
For example
When you connect the current through resistance will not find a change in the current value after resistance

But when you connect the end of the resistance in the Ground
You will notice the hottest resistance and this dissipates energy
And you'll find the current difference on the side of the resistance
